' JOI-IN F. W'HITE, OF KARNES CITY, TEXAS.

HAY-PRESS;

Application filed August 9, 1918.

To'aZZ whom #may concern.'

Be it known that I, JOHN F. VHrTm'a citizen of the United Sta-tes,residing at Karnes City, in the county of YKarnes and Y State of Texas,have invented new and use- Vvide a device of this character which issimple and durable in construction, reliable and efficient in operationand one which can be manufactured and placed upon the market at a.minimum cost.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated Vin the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation of the invention.

Fig. 2 is a plan view thereof.

Fig. 3 is a horizontal section.

Fig. 4 is a sec-tion of the operating means on the line 1 4: of Fig. 2.

As shown in these views the invention Y comprises the press box 1 havingthe hopper 2 in its top andthe bale box 3 extending from one endthereof. The top 4l of this bale box is flexibly connected with thepress, and the upward movementA of the rear end thereof is controlled bythe bar 5 under pressure of the springs 6. 7 represents the spring dogspreventing the re-bound of the binding block 8 on the return stroke ofthe plunger. 9 represents the plunger providedVVV with the plunger rod10.

11 represents the operating member which is pivotally mounted on theplatform'12 by the bolt 13, said platform being carried by the beams 1-1forming extensions of the lower part of the press.

Specification of Iietters Patent. 1

Serial No. 249,149.

The o eratinO' member 11 is com osed of nected together by thediametrically arranged bolts 17 and sleeves 18 on said bolts hold saidparts in spaced relation. As will be seen the bolts 17 and the main bolt13 are in the same vertical plane. Each of the parts 15 and 16 isprovided with a cam or race-way 19 which consists of two substantiallyparallel part-s connected together at the ends by the curved parts. Apin 20 on the plunger rod 10 engages said cams and said plunger rod isprovided with a dog 21 which is adapted to engage with the sleeve 18when the operating member 11 is rotated so that the plunger rod is movedforward to carry the plunger head into pressing action. As will be seenthe dog is slightly in ad Vance of the pin 2O so that when the dog isengaging the rearmost sleeve at the beginning of` a pressing stroke thepin will be at the beginning of the curved parts of the cams. Thus whenthe operating member is moved the dog will pivot on the sleeve and thepin will be engaged by the curved part of the cams, so that said pinwill pass from one side of the cam to the other in a half revolution ofthe operating member. On the continual rotation 'of said member theextreme end of the plunger rod will be pressed outwardly by the othersleeve, while the lirst sleeve will pass from the dog so that the spring22, connecting said plunger rod with the platform, will cause said rodto spring back into normal position with the dog engaging the othersleeve. In this operation the pin 20 passes along the parallel parts ofthe cams. It will thus be seen that a quick return of the plunger issecured.

lVhile the operating device may be rotated by any suitable means I showa sweep 23 secured to the top part of the operating member by the bolts13 and 21, said sweep being braced by the beams 25 engaged by the bolts17.

What I claim is 1. A baling press comprising a-press box,

2. A baling press comprising a press box,
